ASUS ROG Strix Z790-A Gaming LGA 1700 - BIOS 1801 - Update?

I just put a ASUS ROG Strix Z790-A Gaming LGA 1700 MB into my new build (with a 14th Gen i7) I guess I need to update the bios to make this work. I have the 1801 bios on my USB stick with FAT32 and renamed properly. This is what happens....

  1. Plug in PSU / ( DON'T turn on PC )
  2. Plug in USB stick
  3. Press Flash button / Light turns FLASHING GREEN
  4. Release Flash button / Light goes SOLID GREEN after 3 seconds
  5. Nothing else happens. Just stays solid green ..... but BIOS does not seem updated.

It happens so fast, from the time I push the button until the light goes solid green is like 3 seconds.  What could be wrong ? Or just any thoughts ??? 

Thank you

Hi,

A couple of questions.

  1. Has the new CPU been installed or not installed in the motherboard when you've attempted the bios update?
  2. Have you tried using a different USB drive?

CPU was installed. The problem was the usb was GPT not MBR.  With MBR formate it works 🙂

Great you got it all sorted out. 😄

Issues with the USB drive is a common issue when updating bios.

Try downloading the BIOS again and unpack it with WinRar, not Windows. If that doesn't work, then try using EZFlash 3 in the BIOS, hopefully that will work.
